Possibility of the abrasive wear resistance determination with scratch tester
(Springer/Plenum Publishers, New York, 2010)
Abrasion wear resistance is very important in many applications and it is not a surprise that there are many laboratory test methods for its determination. In this article, a possibility of the abrasive wear resistance ...
Mock-up testing facilities and qualification strategy for EU ITER TBMs
(Elsevier Science Sa, Lausanne, 2010)
European test blanket modules (TBM) for both European blanket concepts, namely the Helium Cooled Lithium Lead (HCLL) and the Helium Cooled Pebble Bed (HCPB), and their auxiliary systems have been designed in the last years. ...
Failure analysis of the combat jet aircraft rudder shaft
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
This paper analyzes failure causes of the combat jet aircraft rudder shaft (RS) which occurred during the flight mission. A finite element method (FEM), utilized to determine the stress state of the RS subjected to hinge ...
Neural network prediction of brake friction materials wear
(Elsevier Science Sa, Lausanne, 2010)
Wear of brake friction materials depends on many factors such as temperature, applied load, sliding velocity, properties of mating materials, and durability of the transfer layer. Prediction of friction materials wear ...
Abstract metric spaces and Sehgal-Guseman-type theorems
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
Recently, Raja and Vaezpour [P. Raja and S.M. Vaezpour, Some extensions of Banach's contraction principle in complete cone metric spaces, Fixed Point Theory Appl. 2008, 11 pages, doi:10.1155/2008/768294. Article ID 768294] ...
Estimation of the number of trays for natural gas triethylene glycol dehydration column
(Elsevier, Amsterdam, 2011)
The paper deals with the tray-to-tray method for determining the required number of trays in columns with intensive entrainment of liquid when the operating line of the "dry working regime" is not straight and with a small ...
Gaussian interval quadrature rule for exponential weights
(Elsevier Science Inc, New York, 2012)
Interval quadrature formulae of Gaussian type on R and R+ for exponential weight functions of the form w(x) = exp(-Q(x)), where Q is a continuous function on its domain and such that all algebraic polynomials are integrable ...
Determination of gun propellants erosivity: Experimental and theoretical studies
(Elsevier Science Inc, New York, 2010)
Requirements for higher and higher performances of contemporary guns intensify investigations concerning influence of various factors on barrel erosion. The most important parameter for the life of the gun is the type of ...
Ion mobilities and transport cross sections of daughter negative ions in N2O and N2O-N-2 mixtures
(IOP Publishing Ltd, Bristol, 2013)
A pulsed Townsend apparatus is used to measure the mobility of a single negative ion species in N2O and N2O-N-2 gas mixtures. The range of the density-normalized electric field, E/N, is 6.5-100 Td (1 Townsend = 10(-17) V ...
Time optimal motions of mechanical system with a prescribed trajectory
(Springer, Dordrecht, 2011)
The problem of time minimization of a holonomic scleronomic mechanical system on a prescribed trajectory between two specified positions in configuration space is solved. The generalized force with restricted coordinates ...
